International Science Olympiad

The International Science Olympiads are a group of worldwide annual competitions in various areas of the formal sciences, natural sciences, and social sciences. The competitions are designed for the 4-6 best high school students from each participating country selected through internal National Science Olympiads, with the exception of the International Linguistics Olympiad, which allows two teams per country, the International Olympiad on Informatics, which allows two teams from the hosting country, and the International Junior Science Olympiad, which is designed for junior secondary students and also allows two teams from the hosting country. Early editions of the first Olympiads were limited to the Eastern Bloc, but later they gradually spread to other countries.^[1]
